4 Claims.

This invention relates to a stoker for a boiler firebox and primarilyhas for its object the provision of a novel and improved form ofconstruction whereby the application of the stoker to the firebox issimplified and rendered more convenient.

There are in commercial use, fireboxes of many diiferent types forstationary boilers as well as for locomotive boilers, and the fireboxwalls may slope at various angles with respect to the horizontal. Inapplying to a firebox, a stoker of the type in which the forward end isattached to the firebox wall, it is apparent that difficulty isencountered in providing a stoker which is adapted for attachment tofirebox walls of different slopes. Many stokers in use today have aflange formed integral with the forward end of the stoker conduit, andthe conduit is fastened to the firebox wall by bolting the flange to thefirebox Wall. However, in such instances, it is obvious that the forwardend of each stoker must be particularly designed in accordance with theslope of the firebox wall of each particular installation. Therefore,instead of one stock forward conduit, it would be necessary to design aforward conduit to meet the particular conditions of each firebox forwhich an installation is to be made.

In the application of stokers to a firebox in which the forward conduitis not provided with an integrally formed fiange but a separate bracketis provided, it is necessary todrill holes in the proper places in thestoker conduit walls before the stoker can be assembled in place.

It is therefore a further object of my invention to provide a stokerthat can be installed on a firebox irrespective of the slope of thefirebox wall and eliminate the necessity of performing furtheroperations on the stoker forward end other than merely attaching it tothe firebox wall.

In stokers of the type wherein the blast chambers and distributing tableare attached to the delivery end of the conduit it may be foundnecessary to change the slope of the conduit slightly to maintain thedistributing table in a horizontal position or for some other reason itmay be found necessary to slightly change the slope of the conduit. Itis therefore, a further object of this invention to provide means, forsecuring the forward end of the conduit rigidly with the firebox wall,that is adjustable to compensate for such changes in the slope of theconduit, eliminating the necessity of performing any mechanicaloperations on that portion of the stoker adjacent the firebox wall.

Therefore, my present invention addressed to the efficient eliminationof the ills above enumerated, further resides in the novel details ofconstruction, combination and arrangement of parts which will be pointedout in the appended claims, reference being had to the accompanyingdrawing, in which:

Figure 1 is a side view partly in elevation and partly in section of thestoker and associated parts of the boiler firebox.

Figure 2 is a plan View of the construction illustrated in Figure 1.

Figure 3 is an elevational view of the stoker as viewed from theleft-hand side of Figure 1.

Referring more particularly to the drawing, 4 indicates the back wall ofa boiler firebox which may be of any desired construction, and 5indicates the firing opening in the back wall. Disposed Within thefiring opening is a blast chamber 6, and extending forwardly from theblast chamber is a distributing table l. A ledge ta integral with theblast chamber and underlying the distributing table supports the latterand is provided with the opening 5h closely receiving the downwardlyprojecting lug lot of the table for removably securing the table to theblast chamber. Associated with the blast chamber is a fuel conduit 8, ofany desired construction for delivering fuel to the distributing tableI. Disposed between the sides of the conduit and the backhead areangular brackets 9. The angular brackets may be secured to the backheadby means such as studs l9, and nuts I i. The brackets extend rearwardlyfrom the backhead at substantially right angles alongside the side Wallsof the conduit 8, and are secured to the conduit by means such as studs01 bolts l2, and nuts 53. Rearwarol of studs l2 are studs i i, arrangedfor movement in slots 15. Slots iii are constructed as segments of acircle and have for their axis studs l2. It will be observed that theconduit 8 is capable of pivotal adjustment about the studs 2 withrespect to the firebox backwall and between the brackets 9.

From the foregoing it is seen that the conduit 8 may be pivotallyadjusted to any angle necessary to position the distributing table I, ona substantially horizontal line, since the distributing table is movablewith the conduit.

After the conduit 8 is adjusted to the proper angle, nuts 53 and H arethen tightened, thus resulting in the conduit being attached rigidly tothe backhead. Bracket ii is also applied for additional support to theconduit at its lower portion. The length of the bracket I! may beconveniently changed to fit between the conduit and backhead by bendingit.

Thus having fully explained the invention, I claim:

1. In a stoking mechanism for locomotives in combination, a locomotivehaving an apertured boiler backhead, a fuel conduit delivering to theaperture, a blast chamber rigidly attached to said conduit, a removabledistributing table secured to and extending forwardly from said blastchamber and in position to receive fuel from said conduit, means forsecurely attaching said conduit to said backhead, said means permittingpivotal adjustment of said conduit about a horizontal transverse axisthereby providing means for adjusting said distributing table to asubstantially horizontal position.

2. In a stoking mechanism for locomotives in combination, a locomotivehaving an apertured boiler backhead, a fuel conduit delivering to theaperture, a blast chamber rigidly attached to said conduit, a removabledistributing table extending forwardly from said blast chamber, saidtable being secured in fixed relation with said conduit and blastchamber and in position to receive fuel from said conduit, means forsecurely attaching said conduit to said backhead, said means permittingpivotal adjustment of said conduit about a horizontal transverse axis,thereby providing means for adjusting said distributing table to asubstantially horizontal position, and means for securing said conduitrigidly to said backhead after adjustment thereof.

3. In combination, a boiler firebox provided with a firing opening in awall thereof, an upwardly extending fuel conduit positioned outside thefirebox and at its delivery end communicating with said firing opening,fuel distributing apparatus disposed in said opening and being rigidlysecured to said conduit, means for attaching said conduit to saidbackhead, said means permitting pivotal adjustment of said conduit abouta transverse axis thereby providing means for adjusting said fueldistributing apparatus in any one of a number of positions.

4. In combination, a boiler firebox having a 15 firing opening therein,a fuel conduit outside the firebox in communication with said firingopening, a bracket at each side of the conduit adjacent its delivery endrigidly secured to said firebox, means pivotally mounting said conduitat its delivery end in said brackets for movement only about ahorizontal axis extending transversely of the conduit, and means rigidlysecuring the conduit to the brackets in any one of a number of positionspermitted by said pivotal mounting.
